Trados 2015 .doc/.docx target files when Office is not installed

Hi. I've noticed SDL Trados Studio 2015 (Trial version) won't allow saving target files to .doc/.docx when Office is not installed on the computer. SDL Trados 2009 did allow opening a .doc/.docx file, translating it, then saving it in .doc/.docx even if Office is not installed. Is this a limitation of the 2015 trial or a feature of the 2015 full version?
